The original poster's interpretation of the TSB is incorrect. Right up in the header, and again in the middle of the first page, it clearly says that it applies ONLY to 06 and 07 model year vehicles. If your vehicle is a 2005 model or older, this TSB simply does not apply to you.
The TSB is ambiguous because it also lists, in the table, engines that went out of production (for US vehicles anyway) before the 06 MY. Don't be led astray by this error. If the TSB is N/A to your car, whether its content is right or wrong is irrelevant.
